A teenage drinker smashed a bottle into the head of another boy who laughed at him.
The 17-year-old, who cannot be named for legal reasons, left his victim with a gash so deep that his skull could be seen.
Perth Sheriff Court heard the 18-year-old victim had been left permanently scarred.
Depute fiscal Mairi Graham told the court the teenager had been in Blairgowrie with friends when he met up with the accused and another boy at around 8.20pm.
She said: “The complainer was mainly engaged with the other male but saw the accused was holding a bottle.
“The accused spilled this over himself and all those present laughed at him. The accused took a dislike to the complainer laughing at him and hit him on the head with the bottle.
“The bottle did not break but the complainer began bleeding.”
She said the incident led to a scuffle amongst the group, which was broken up and the parties went their separate ways.
The victim was taken to Ninewells hospital for treatment, where medics found he had a 3cm cut which had exposed his skull. The injury has resulted in permanent scarring.
Solicitor Pauline Cullerton, defending, said the teenager “deeply regretted” his actions and wished to apologise to his victim.
The teenager, of Dunfermline, admitted assaulting his 17-year-old victim to his injury and disfigurement on Perth Street, Blairgowrie on November 22 last year.
He was ordered to carry out 100 hours of unpaid work.
